MCQ
In which case the thermal conductivity increases from left to right
  • ✓
    $A l, C u, A g$
  • B
    $\mathrm{Ag}, \mathrm{Cu}, \mathrm{Al}$
  • C
    $\mathrm{Cu}, \mathrm{Ag}, \mathrm{Al}$
  • D
    $A l, A g, C u$
✓

Answer

Correct option: A.
$A l, C u, A g$
$Cu$ is better conductor than $A l$ and $A g$ is better conductor than $\mathrm{Cu}$. Hence conductivity in increasing order is $A l$
